Residual Gastric Volume in Morbidly Obesa Diabetics. A Comparison of 3 Hour Versus Hour Fasting.

14. april 2014 opdateret af: Gunther Peres Pimenta, Cuiaba University
To reduce the risk of aspiration for elective procedures, residual gastric volumes (RGV) have traditionally been minimized with overnight fasting. However, prolonged fasting can also have some adverse consequences and has been abandoned for some procedures in several patient populations with the exception of obese and/or diabetic patients. The aim of this study was to assess RGV in morbidly obese diabetic patients after traditional or abbreviated fasting.

Detaljeret beskrivelse

Patients underwent two endoscopic examinations within two weeks. RGV was measured by aspiration of gastric contentes into a graduated cylinder after traditional fasting (at least 8 hours before the test) and after abbreviated fasting (3 hours with 200ml of water containing 25g of 12.5% maltodextrin). All patients received both oral and written information about the protocol at the outpatient clinic.

All the endoscopic procedures began at 9 AM, and were performed by the same board-certified endoscopist, JMS, who was blinded as to the duration of the fast. The endoscopies were conducted at Gastroclinica, Cuiaba, MT, in the period from April to June, 2013. Sedation was performed by a board-certified anesthesiologist, who was also blinded as to the duration of the fast. The anesthetic regimem included a intravenous bolus of 2 ml of lidocaine hydrochloride (Astra Zeneca, São Paulo, Brazil) followed by 100 to 150mg of propofol before endoscopy. Digital oximetry was monitored throughout the procedure. Patients were positioned in the lateral recumbent position. A flexible electronic videoendoscope (EG2770K; Pentax Corporation, Tokyo, Japan) of 9 mm in outer diameter was used. The main outcome variable was the RGV measured by the endoscopist after aspiration of gastric residue.

Aktiv komparator: Abbreviated fasting
Patients underwent two endoscopic examinations within two weeks. RGV was measured by aspiration of gastric contentes into a graduated cylinder after traditional after abbreviated fasting (3 hours with 200ml of water containing 25g of 12.5% maltodextrin).
